Virtual forest: Eiffel Tower lights up for climate change conference

The symbol of Paris lit up in green transforming into a metallic tree-like structure on the eve of the United Nations climate conference in Paris on Sunday. The author of the light installation, Belgian-Tunisian artist Naziha Mestaoui, named it “1 Heart, 1 Tree.” The project enables anyone with a smartphone to download an app to purchase a virtual tree and add it to the installation. The purchase also contributes to reforestation programs in Brazil, Peru, Senegal, Kenya, France, India and Australia.
